Is it rude to leave a voice message instead of texting?

One camp hears a voice note and feels the warmth of a friend actually talking to them. The other camp hears forty-five seconds they cannot skim, search, or read on a train. Both camps are completely certain the other one is being inconsiderate. Speech carries more than words do; your thumb, hovering over the 1.5x button, disagrees. Settle it.
